Model the network as a graph where every vertex carries bonded value; a cluster of fake identities shares one thin root, like rings of a single cedar trunk, so cut-based analysis exposes it. Vouches also age over a long time horizon, so cheap fresh accounts gain no weight until they survive many epochs of honest work.","stamp":0,"from":"poa15jmr5MX13gtPh4YKq8et2NPzPM1SfJt4hJiZ5SzXHra2","nonce":7,"parents":["73b279c01f0d1866e7cf3f4a5607bb1933a7a1b8ccd16fbaa557c64fea05104b","b5928e1c4c01c5d44f27a0bb951beb5f7930d279a1841197dd425cb920af0b7d"],"ts":1793313144,"cid":"poa-mainnet-1","sig":"5zQSxV7AmsM9k6EQjX9MFXE62Jdu56kvmvgE7Ro6aMbWGag9n2GgdMxzpW2s6n91KqRnDSUnE5Mn1WkQLLGVCRaG"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:50:40.656Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
